New biorepository aims to unlock secrets of kidney disease in sickle cell patients
NCT ID NCT07064174
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is building a special collection of blood and urine samples from 800 adults with sickle cell disease or sickle cell trait, along with some healthy volunteers. Researchers will use these samples and medical records to learn how kidney disease starts and gets worse in people with the sickle cell gene. The goal is to find early warning signs and develop better ways to protect kidney health.
